Amenbo can be one of the smallest Badnik models that Dr. Eggman has created, as being based on water striders. It has a cyan-colored body with metallic spindly legs. Also, located on the rear of Amenbo is a sizable fan used to navigate the surface of the water.
The Amenbos appears exclusively in Tidal Tempest. It will attempt to shoot small projectiles at Sonic, although it does so rather sporadically. The worn down version of Amenbo in the Present and Bad Future is not very different from its pristine version, except the fan on its body is broken, it moves slower and it never fires projectiles.
Amenbos are rather rare enemies, as they only appear in areas with large water surfaces, something which Tidal Tempest has very few of. Amenbos can easily be defeated with a simple Spin Jump. Like every Badnik in the game, the Amenbos are powered by Little Planet flower seeds which will pop out of them when they are defeated.
